Lactic Acid Myth!

We’ve all learned that lactic acid build-ups are bad and cause muscle soreness. Turns out that’s not true, our muscles actually use it as a fuel.

T-Nation did a piece on this a year or so ago (could be longer). Just goes to show, T-Nation is ahead of the game!

Actually lactic acid can be a contributor to muscle soreness especially DOMS (delayed, if it is not evacuated or used by the muscles at the same rate that it is produced.
By the way, the heart is the biggest utilizer of lactic acid as energy…
Research is suggesting that NO (biproduct) and a whole other bunch of physiological processes are involved in contributing to muscle soreness.

If anyone can be more specific about the production of NO in the body it would be great. It’s been a while since I studied all this.
